The correct figure is the rectangle containing a six-sided figure whose top and bottom edges lie on the rectangle, whose left and right corners touch the middle of the rectangle's sides, and whose two side corners are joined by a horizontal line.

The given figure is a tall rectangle with a horizontal line across it. From the two ends of this line, two slanting lines run down and inward to the base, so the lower part forms a trapezium with a flat bottom that narrows downward.

In the correct figure, take the outer rectangle, the horizontal middle line and the two lower slanting edges of the six-sided figure: these edges go from the ends of the middle line down to two separate points on the base, giving exactly the same narrowing trapezium with a flat bottom.

In the two figures with a diamond, the lower slanting lines meet at a single point on the base and form a triangle with no flat bottom. In the figure with arrow-shaped (chevron) lines, the slanting lines start from the left side and do not hang from a horizontal line. So the given figure is embedded only in the six-sided-figure option.
